        Thank you very much for attantion to my problem. 
    Solution you have proposed is very understandable, but I would
    like to find a way to use X.25 protocol as direct transport for 
    SNMP (in your terms: SNMP/X.25). The same as IPX or DDP could 
    be optional transport protocol for mapping SNMPv2 (according to
    RFC 1449). Is it possible ?

    In this case Packet Switch software have to be able to resolve
    IP and UDP protocols, could I avoid it ?
